How can I diagnose a fuel delivery problem on a 2003 VW Jetta GLI 2.8L

you can unhook the fuel line where it connects to the fuel rail and turn the key on and see if you get fuel but it's risky you don't want it to spill over the engine. you may just need a new filter or maybe an intermittent short at the fuel pump. could even just be the power supply plug for the fuel pump

The oil light came on and it says no oil pressure stop the engine. What would cause this?

This problem can be caused by; low engine oil, bad oil pump, or bad or disconnected oil pressure switch. Please identify which engine your car has and which model Jetta it is (2.0T, 2.5,GLI, TDI or Value Edition) in order to establish the location of the components.

I have a 2002 VW Jetta GLI and my check engine light has been on for 3 days now. Is it ok to just drive the car for now and dont take the car in? What will happend if I don't get the car checked out?

I would have it checked out and SOON. Those lights come on for a reason. Namely a sensor has triggered identifying a fault. The longer you drive on it the more things can and WILL get damaged. Don't mean to scare you, but they do serve a purpose. Stop by any good parts store (Autozone, Advance, etc...) and have them do a free fault scan and FIX IT.

We recently replaced a glowplug on our 2003 VW Jetta tdi. We had to disconnect the power source. Since then, the door alarm wont stop ringing. We can't find the factory reset code. Can you help? Oh, it has...

Removing the battery connection for this procedure will cause diagnostic trouble codes to be stored in the engine control module. Erasing these DTCs and resetting the readiness code will require Volkswagen scan tool VAG1551/1552 or equivalent. The same results will occur when disconnecting engine management components while the key is in the on position. Some driveability problems may be noticed until the system re-adapts to operating conditions. OBD II readiness codes, which may be required for emissions testing, may also be erased. Convenience electronics (alarm systems, interior light control, power locks, mirrors, and windows) may need to be re-set using a VAG 1551/1552 or equivalent sacan tool.

How do i fix emission codes p1131 p1151 p0171

Some 2001-2003 F-150, 2004 F-150 Heritage and 2001-2003 E-150/250 vehicles equipped with a 4.2L engine may exhibit the malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P1131 and/or P1151 (system too lean bank 1 or 2). This condition may be due to leaking isolator bolts/port gaskets in the upper-to-lower intake manifold mounting area. This condition is sometimes intermittent and may not be apparent on a warmed-up engine.


Perform a self test. If DTC P1131 and/or P1151 are the only codes stored in the powertrain control module (PCM) proceed to Step 2. If any additional DTCs are present, follow normal diagnostic procedures found in the PC/ED Manual.

Remove the upper intake and replace only the port gaskets (9H486) and isolator bolt assemblies (9S479). The new isolator bolt assemblies use a rubber material that is green in color, do not install the old isolator bolt assemblies with the black rubber material. Do not replace any other intake parts or gaskets.
While the upper intake manifold is removed, check the exhaust gas recirculation (EGR) orifices that are pressed into each primary port of the lower intake manifold. If any of the orifices are plugged with soot, clean and unplug them with a pick and solvent.
